Ayu's concerts and tours are most entertaining in every aspect overall.

Misia overall

Namie Amuro ~ She can sing and dance at the same time PERFECTLY.

Voting by how much they can entertain me live, I say Hikaru, Ayu, Kuu and Ringo Shiina. All the others are either flat out boring or just really suck at singing (or both >_<), lol. :\

Ayu and Namie

alan - She has an amazing voice and is a great performer
Chihiro Onitsuka - Just simple and clean :yes

since I'm addicted to ayu..i'm voting for her..haha :P

voted for kumi, boa and ai otsuka :yes their live performances are always so entertaining to watch and they just really know how to bring it

Ayu

ayu
kuu
namie
crystal
ai

I only voted for Kuu cause I'm a stan, lol.

But, seriously, I have only been blown away by Kumi lately. Even with the most basic stage, where there is less effects to pump into the performance, she still owns it. Kumi has, in my opinion, unmatched stage presence. She has so much confidence and personality it pretty much bursts out of the TV. She looks so happy to be there and like she's having so much fun.

Ayumi Hamasaki
Koda Kumi
BoA
Namie Amuro

Ayumi Hamasaki
Koda Kumi

Ayumi and Ai Otsuka takes the win - the have the whole package, but Ayu's voice is more to my liking.
Also voted for Hikki & BoA - Hikki's great efforts and BoA's amazing coreography.

This is weird - I barely every listen to Ai on my walkman. I'm a big fan of YUI's and listen to Namie very often but when it comes to live - well, I can barely even watch Namie >.< And YUI is often very similar, but I don't mind just sitting there and listening but she's not an entertainer imo.

Definitely Namie Amuro because her dancing is gorgeous and singing on stage really shows how strong and amazing her voice is. <3

Ayumi Hamasaki by far because she is THE entertainer !!! She create her whole show ! it's like a musical comedy ! it's fantastic ! I'm never tired to see her concerts in dvd =)

Of course Nana Mizuki is also my favorite equal to ayu for differente reasons ! She always sings live even better than studio version, she is full of energy and power, great animations, good ideas etc...

Koda Kumi is very good too but I like not enough songs in her discography for appreciate completely her concerts but I've do admit she is very entertaining =)

Namie amuro lives is boring to me I've looked at several of her concerts because I like her music but in live just no for a lot of reasons even she dancing very well but I don't want to made a drama so I will not say anything.

Utada is not so amazing in the last live i've seen she is breathless quickly better in studio imo !

They are the only female singer that I've looked at their concerts because I really like them =)

Ayu by far!

angela aki

When it comes to live performances, I prefer Ayumi.
However all of those artists on the poll also pull great performances, specially Namie and Kuu.
